Bead on a wavy wire

A bead slides down on a frictionless wire, starting from rest at point A. The section from A to B is straight while the section from B to C is wavy (with wavelength λL\lambda\ll L). The total length of the stretched wire is 3L3L. If L=50 cmL=50~\text{cm}, determine the time in seconds it takes for the bead to reach point C. Assume that the bead slides smoothly at all times.
